产品描述 | RepSox (ALK5 Inhibitor II) is a TGFβR-1/ALK5 inhibitor that selectively inhibits the binding of ATP to ALK5 and the autophosphorylation of ALK5 (IC50=23/4 nM). RepSox induces adipogenesis in MEFs cells. |
靶点活性 | TGFβRI:4 nM |
体外活性 |
方法:小鼠胚胎成纤维细胞 MEFs 用 RepSox (10 µM) 处理 10 天,使用 oil red O 染色检测细胞脂肪。 结果:RepSox 处理的 MEFs 中出现了许多脂肪细胞样细胞,脂滴的 oil red O 染色证实了脂肪细胞分化。[1] 方法:绵羊成纤维细胞用 RepSox (10-25 nM) 处理 3 天,使用显微镜观察细胞形态。 结果:在 RepSox 处理三天后,绵羊成纤维细胞获得了显著不同的形态,并从纺锤形转变为具有更多聚束的细长形状。[2] |
体内活性 |
方法:为检测对肠内神经胶质细胞 EGCs 分化的影响,将 RepSox (3-10 mg/kg in 0.5% CMC-Na) 灌胃给药给 GFAP-Cre:Rosa26-tdTomato 小鼠,每天一次,持续两周。 结果:RepSox 可以促进 EGCs 转化为神经元,并改善体内胃肠道运动。[3] 方法:为检测体内抗肿瘤活性,将 RepSox (5-20 mg/kg) 腹腔注射携带骨肉瘤 143B 的 nude 小鼠模型,每两天一次,持续三周。 结果:RepSox 有效地抑制了骨肉瘤的生长,并且在裸鼠中具有低毒性。[4] |
激酶实验 | The kinase domain of ALK5 is cloned by PCR and expressed in a baculovirus/Sf9 cells system. The protein is 6-His tagged in the C terminus and purified by affinity chromatography using a Ni2+column, and the obtained material is used to assess compound activity in an autophosphorylation assay. Purified enzyme (10 nM) is incubated in 50 μL of Tris buffer (Tris 50 mM, pH 7.4; NaCl, 100 mM; MgCl2, 5 mM; MnCl2, 5 mM; and DTT, 10 mM). The enzyme is preincubated with different concentrations of RepSox (0.1% DMSO final concentration in the test) for 10 min at 37°C. The reaction is then initiated by the addition of 3 μM ATP (0.5 μCi γ-33P-ATP). After 15 min at 37°C, phosphorylation is stopped by the addition of SDS?PAGE sample buffer (50 mM Tris-HCl, pH 6.9, 2.5% glycerol, 1% SDS, and 5% β-mercaptoethanol). The samples are boiled for 5 min at 95°C and run on a 12% SDS?PAGE. Dried gels are exposed to a phosphor screen overnight. ALK5 autophosphorylation is quantified using a Storm imaging system[1]. |
细胞实验 | RepSox is dissolved in DMSO and stored, and then diluted with appropriate media (DMSO 1%) before use[1]. To test anti-TGF-β activity of compounds, HepG2 cells are seeded in 96 well microplates at a concentration of 35000 cells per well in 200 μL of serum-containing medium. The microplates are then placed for 24 h in a cell incubator at 37°C, 5% CO2 atm. RepSox dissolved in DMSO are then added at concentrations of 50 nM to 10 μM (final concentration of DMSO 1%) for 30 min prior to the addition of recombinant TGF-β (1 ng/mL). After an overnight incubation, the cells are washed with PBS and lysed by addition of 10 μL of passive lysis buffer. Inhibition of luciferase activity relative to control groups is used as a measure of compound activity. A concentration?response curve is constructed from which an IC50 value is determined graphically[1]. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
